SPECIFICATION forming part of Letters Patent No. 722,624, dated March 10, 1903. Application filed December 1, 1902. Serial No. 138,448. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE B. PICKOP, a citizen of the United States, residing at New Britain, Hartford county, Connecticut, have invented certain new and useful Improvements in Detachable Hinges, of which the following is a full, clear, and exact description.

This invention relates to improvements in hinges.

Among the objects of my invention is to provide in detachable hinges certain new and useful features of construction whereby great strength and durability are attained and whereby such hinges may be produced at comparatively small cost. Such hinges may be used wherever desired, but are particularly convenient when fitted to screen-doors, stormwindows, or the like. The attachment of such doors or windows is effected easily and will not jam or Wedge. Hence they maybe removed readily and without the necessity of unscrewing any part or removing any connection between the hinge-leaves. In the form shown the hinge is fitted with a spring whereby the device carried by the hinge is normally held closed.

In the drawings, Figure 1 is a front elevation of myinvention. Fig. 2 is a front elevation of a detail of construction. Fig. 3 is a plan View of Fig. 1. Fig. 4 is a top view of my improved hinge as applied.

A represents a portion of a screen-door.

B represents a portion of a door-casing.

C is a hinge-leaf pivotally connected to another hinge-leaf D. In the particular form shown thesehinge-leaves C D are each provided with offset ears C C and D D, respectively. These ears are perforated and a pintle or pivot-pin E passes through the same to afford the proper pivotal connection.

F is a spring which may surround the pintle E, the ends of the spring overstanding the hinge-leaves C D, so that tension of thespring may be applied in a direction to cause said leaves to normally move in the desired direction-for example, in a direction to normally cause the door A to close.

F is what I may term a keeper-plate, which may be securely fastened to the doorcasing B. The keeper-plate F bears a studlike device G on its face. At its lower edge said keeper-plate is provided with an outwardly directed flange H, preferably so shaped as to form a rearwardly-inclined shelf or ledge, as best seen in Fig. 3. The incline of the ledge in the preferred form corresponds substantially to the beveled edge of, the hinge-leaf D, so that when the parts are assembled, as shown in Fig. 1, the extreme lower edge of the hinge-leaf D projects down into the pocket thus formed and is prevented from displacement. The hinge-leaf D is provided with a slot therein, which has an enlarged passage of a suitable size to admit of the passage of the head of the stud G, and the end of the slot is narrower and of a wid th corresponding substantially to the diameter of the shank of the stud. While it is obvious that the narrower portion of said slot may extend only above the stud-head passage, it is preferable to have the narrower portion of said slot extend both above and below, because in such event it permits of the reversibility of the hinge. It should be observed that the leaf D is offset-that is, the plane of its rear side is slightly out of the plane of the rear side of the leaf C. This allowance is made because in use the hinge-leaf D stands away from the casing B the thickness of the keeper-plate F.

From the foregoing description the operation of the device will be readily seen. The hinge-leaf C is screwed or otherwise fastened to the door A or other device. The keeperplate F is screwed or otherwise fastened to the supporting frame or casing B, with the stud G uppermost in all cases. The door is then so positioned as to permit the user to slip the hinge-leaf C into place by passing the enlarged part of the slot in the hingeleaf D over the head of the studG. The under side of the head of the stud is spaced apart from the surface of the keeper-plate F the thickness of the hinge-leaf D. The consequence is that when the hinge'is slipped down the head of the stud G overstands the hinge-leaf D, as shown in Fig. 1, and the lower edge of the hinge-leaf projects down into the pocket back of the flange H. When the parts are thus assembled, the flange II and the stud G both serve to securely hold the leaf D in place. When they are firmly united, they may be readily detached at any time, since there is nothing to become wedged or jammed. It is preferred that the flange H should be formed, as shown in the drawings, with a recess or pocket to the rear thereof, so that it will, in addition to supporting the hinge-leaf D, aid in preventing the hingeleaf D from being pried off. Obviously, however, its function as a support merely is a new and useful one. The particular formation or design of the separate parts of the hinge, including the keeper-plate, may be modified in many ways from that particularly shown and described herein.

By the foregoing construction it is obviousthat sheet metal may be employed in the production of the various parts. Hence hinges may be rapidly and economically prodnced.

WhatI claim is 1. In a hinge, two leaves, means of connection between the same, a slot in one of said leaves, a keeper-plate, a stud supported thereby, a portion of the slot being sufficiently large to admit of the passage of the stud-head and arranged to admit of a sliding engagement between said keeper-plate and said slotted hinge-leaf, a ledge or abutment on one of said parts, said ledge or abutment enacting with the stud in holding the hinge in place.

2. In a hinge, two leaves, means of connection between said leaves, a keeper-plate, 35

a stud thereon in the upper portion thereof and an outwardly and upwardly directed ledge or abutment in the lower portion thereof forming a pocket, a slot in one of said hinge-leaves, one part of the slot being of such a size to admit the passage of the studhead, another part of the slot being of a width corresponding substantially to the diameter of the stud-shank.

3. In a hinge, two leaves, means of connection between the same, a slot in one of said leaves, a keeper-plate, a stud supported thereby, the middle part of said slot being of sufficient size to admit of the passage of the stud-head, the upper and lower ends of said slot being of less width and arranged to admit of a sliding connection between the keeper'plate and the slotted hinge-leaf, a ledge or abutment on the lower face of the keeper-plate coacting with the stud in holding the hinge in place.
